摘　　要：目的探究三维斑点追踪技术联合心肌性能指数(Tei)评估急性心肌梗死(AMI)患者经皮冠状动脉介入治疗(PCI)后心功能的变化。方法选择2018年1月至2020年4月于中国人民解放军陆军第81集团军医院收治的AMI患者96例作为观察组,并选取同时期来院的健康体检者96例作为对照组。术前采用三维斑点追踪技术联合Tei指数评估两组的心功能、左心室应变量、Tei指数水平,术后对观察组患者进行重复检测;对比两组术前及观察组术前、术后的心功能、左心室应变量、Tei指数水平差异。结果术前,与对照组相比较观察组患者的左室舒张末容积(LVEDV)、左室收缩末容积(LVESV)、Tei指数水平显著性升高,而左室射血分数(LVEF)、左心室整体纵向应变(LVGLS)、左心室整体圆周应变(LVGCS)、左心室整体径向应变(LVGRS)及左心室整体面积应变(LVGAS)水平均显著性降低,组间比较存在统计学差异(P<0.05);与PCI前相比,观察组患者PCI后LVEDV、LVESV与Tei指数水平显著降低(P<0.05),而LVEF、LVGLS、LVGCS、LVGRS及LVGAS水平显著升高(P<0.05)。结论AMI患者接受PCI前、后心功能的改善程度,可由三维斑点追踪技术联合Tei指数定量评估,为临床提供客观的科学证据。Objective To investigate the changes of heart function reviewed by Three-dimensional speckle tracking imaging(3D-STI)combined with myocardial performance index(Tei index)in patients with acute myocardial infarction(AMI)after percutaneous coronary intervention(PCI).Methods AMI patients(n=96)were chosen into observation group and healthy volunteers(n=96)were chosen into control group from Hospital of Chinese PLA the 81st Group Army from Jan.2018 to Apr.2020.Heart function,left ventricular strain and Tei index level were reviewed by using 3D-STI combined with Tei index in 2 groups before PCI,and reviewed again in observation group after PCI.The difference in heart function,left ventricular strain and Tei index level were compared between 2 groups before PCI,and in observation group before and after PCI.Results Before PCI,left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV)and Tei index increased significantly and left ventricular ejection fraction(LVEF),left ventricular global longitudinal strain(LVGLS),left ventricular global circumferential strain(LVGCS),left ventricular global radial strain(LVGRS)and left ventricular global area strain(LVGAS)decreased significantly in observation group compared with control group(P<0.05).In observation group,LVEDV,LVESV and Tei index decreased significantly(P<0.05),and LVEF,LVGLS,LVGCS,LVGRS and LVGAS increased significantly after PCI compared with those before PCI(P<0.05).Conclusion The improvement of heart function can be reviewed by using 3D-STI combined with Tei index in AMI patients before and after PCI,which can provide objective and scientific evidence for clinical practice.
